PHP 8.0.26 Released!

The AllowDynamicProperties class

(PHP 8 >= 8.2.0)


This attribute is used to mark classes that allow dynamic properties.

Class synopsis

final class AllowDynamicProperties {


Dynamic properties are deprecated as of PHP 8.2.0, thus using them without marking the class with this attribute will emit a deprecation notice.

class DefaultBehaviour { }

class ClassAllowsDynamicProperties { }

$o1 = new DefaultBehaviour();
$o2 = new ClassAllowsDynamicProperties();

$o1->nonExistingProp true;
$o2->nonExistingProp true;

Output of the above example in PHP 8.2:

Deprecated: Creation of dynamic property DefaultBehaviour::$nonExistingProp is deprecated in file on line 10
